We report two experiments aiming to define how experience and stimulus enactment affect multisensory temporal integration for ecologically-valid stimuli. In both experiments, a number of different dance steps were used as audiovisual displays at a range of stimulus onset asynchronies using the method of constant stimuli. Participants were either professional dancers or non-dancers. In Experiment 1, using a simultaneity judgment (SJ) task, we aimed at defining — for the first time — the temporal window of integration (TWI) for dancers and non-dancers and the role of experience in SJ performance. Preliminary results showed that dancers had smaller TWI in comparison to non-dancers for all stimuli tested, with higher complexity (participant rated) dance steps requiring larger auditory leads for both participant groups. In Experiment 2, we adapted a more embodied point of view by examining how enactment of the stimulus modulates the TWIs. Participants were presented with simple audiovisual dance steps that could be synchronous or asynchronous and were asked to synchronize with the audiovisual display by actually performing the step indicated. A motion capture system recorded their performance at a millisecond level of accuracy. Based on the optimal integration hypothesis, we are currently looking at the data in terms of which modality will be dominant, considering that dance is a spatially (visual) and temporally (audio) coordinated action. Any corrective adjustments, accelerations–decelerations, hesitations will be interpreted as indicators of the perception of ambiguity in comparison to their performance at the synchronous condition, thus, for the first time, an implicit SJ response will be measured.

Many studies of auditory temporal integration by pathological ears have used listeners with an abrupt high-frequency hearing loss. While this configuration may lend itself to use of the listener as his own control, it presents the opportunity for detection of the low-frequency energy of the brief-tone bursts. This study was designed to assess the role of low-frequency energy in the determination of brief-tone thresholds of listeners with such abrupt high-frequency losses. Low-frequency energy was reduced to subthreshold levels by passing the brief tones through a filter system which had a sharp high-pass characteristic. For both normal and impaired listeners, no significant differences in threshold were found between filtered and unfiltered brief tones. Thus, we must conclude that although the opportunity for off-frequency detection is present, the abnormal temporal integration functions cannot be attributed to stimulus artifact.

Investigations of the threshold for dark interval and backward masking have indicated that duration of the visual sensory trace is inversely related to MA. Based on these findings, it was predicted that lower MA Ss would fuse temporally separated halves of segmented figures at longer ISIs than higher MA Ss. Ten pairs of visual stimuli were exposed tachistoscopically so that each half of a pair would appear as meaningless segmented lines but, when fused, would be perceived as a drawing of an animal. Failure to confirm the prediction was discussed in terms of the influence of cognition on sensory threshold experiments.
